Pyrolysis is a thermochemical decomposition of organic material at temperatures between 400 ° C and 900 ° C without the presence of oxygen or other reagents . The pyrolytic breakdown of wood produces a large number of chemical substances . Some of these chemicals can be used as substitutes for conventional fuels . The distribution of the products varies with the chemical composition of the biomass and the operating conditions. Pyrolysis Plant include 45-52% tire oil, 35% carbon black; 12-15% steel wire; 5-8%. Tire oil is also called fuel oil, can be directly sold (they are also used for processing or used for boiler combustion, bath center, restaurants, burning fuels such as floor brick) or deep processing into organic solvent with refining equipment and automotive fuel, etc.
